-setting presses in which more than one eyelet or fastener is attached to goods at the same time.`

The Object of my invention is to provide a convenient, easily adjusted and accurately operable gang-die attachment for setting presses and. consists in the improvements hereinto be described.

-vices which constitute the setting press attachment; Fig. 2 is a bottom plan view of ,the upper die plate; Fig. 3 is a top plan View of the lower die plate; Fig. 4 is a side elevation, partly in section, of the setting attachment shown in Fig. 1; Fig. 5 is a cross sectionon an enlarged scale of a portion of the attachment shown in Fig. l on the line 5-5; the upper die plate being shown in elevated position; and Fig. 6 is a cross sectional view similar to Fig. 5 showing the parts in closed setting position.

The base plate A of my gang-die setting attachment 1s provided with means such as the screw b for attachment to the bed B of a setting press, the base plate A being screw threaded for the reception of the screw b.

Postshl are screwed into the base plate A from above and constitute front guides and stopsforthe work holding plate H which is normally held elevated against the heads of the osts h by means olf coiled springs h whic surroundthe said posts. This work holding plate is also perforated at 'h2 to accommodate the lower setting dies D. Upon the work holding plate H there are mounted adjustably the rear gage I and end gage J, the rear gage I being slotted at t to admit the shank of the binding screw I and the end gage J being slotted at j to accommodate the set screw J. On the base plate A `there are mounted vertical guidingl member edge with screw threaded apertures to hold the upper die members D, each of which has a screw lthreaded shank .which enters a screw threaded hole in the' upper reciprocating plate E. A boss F is formed on the upper die plate E into which the plunger G of the setting 'press may be inserted and in which it may be held by the set screw f. The adjustment ofthe up er die members D in the plate E is e'ectedD in the following manner and by the following devices: As the shanksl of the upper die members are screw threaded they can obviously be turned up or down to any desired height in the setting attachment.

1n the manufacture of the upper die plate, after the holes for the die members D have been screw threaded, holes are bored from the front of the die plate to receive' the binding screws e2 and when these holes have been suitably threaded, saw cuts e are made in the plate extending from the screw threaded holes for the die'members D into the body of the plate a suitable distance so that a tongue is left between thesev two saw cuts. When the die members D are adjusted to the proper height the binding screws e2 are set up soy as to draw the screw threaded end of the integral tongue between the saw cuts e tightly against the screw threaded shank of the die member, thus holding the latter securely in its previously adjusted position. I have shown the die members I), D',- as adapted to attach a snap fastener member, such as formed by the cap N and securing collet O (see Figs. 5 and 6) to the flap of a glove or other garment indicated at M (Fig. 6). The cap art of the socket member is temporarily he d in the upper die member D by the following devices: Three short pinsv K are inserted in the side of the die member D and the holding clips c, which are suitably perforated, areslipped over these pins. The die member D has a groove L turned in its surface and a clip girdle L consisting of a split spring ring 1s snapped over the upper ends of the clips c holding them securely in place and providing yielding means by which, when a snap fastener cap piece such as N is pressed u against the lower face of the die the fastener member may be held in proper position for the setting operation. As the above described gang-die setting attachment is ventirely-self contained, it reuires no painstaking adjustment in the set- -tmg press. Setting presses such as are usu-` ally em loyed for work of the character idescribed ave lower die attachments for smgledies such as'the screw b, in proper alinement with the reciprocating plunger'G and this alinement of the parts of the press is all that is necessary to insurey the proper operation of my die setting attachment, for the reason that the attachment itself provides all the necessary devices for adjustment and for accurately' guiding the operative parts during all their movements. By adjusting the rear gage I and end gage J all the garments of a given lot, say of gloves, may have their snap fasteners quickly and accurately attached with the assurance that the spacing and placing of fasteners on thel goods will be uniform throughout the series. When all the work appropriateto the given attachment is finished it can be detached from the setting press in almoment and 'another similar attachment previously prepared can be substituted in its .place without requiring any delay for adjustment of parts.

A further practical advantage of my improved press attachment lies in the facility with which tw or more-fasteners can be at- 'taclied without previous perforation of the lglove or other article of apparel;by causing descent of the up er die head compels the plate H to descen against the' stress of the springs L, allowing the final setting operation 'to take lace. Heretofore, lsingle dies have been use with spring sustained sleeves to sustain the goods and compel self erfora tion by the fastener eyelet. But w yen the gang-dies have been used or fasteners attached in two or more places to the same article it'has been necessary to mark the goods so accurately that the fasteners shall be uniformly and properly spaced; where such marking is necessary it is just as Well to perforate the goods beforehand as to mark them, so that in such cases, self perforation by the eyelet part of the fasteners is of no particular practical advantage. By the arrangement above described which includes the work holding plate H Which itself carries the gages I and J, a self erforating setting attachment is provided wllfereby two or more fasteners may be set at the same time and all of the garments of a given lot have their fasteners placed thereon uniformly and accurately; and as the marking or preliminar perforation of the goods -is obvlated muc time will in the aggregate .be saved by the fem loyment of my improved attachment.Y
